Processed multibeam bathymetry grids from the Porcupine Abyssal Plain Sustained Observatory (PAP-SO) (DY130, 2021)

Multibeam swath bathymetry data at the Porcupine Abyssal Plain Sustained Observatory (PAP-SO) were collected with a hull-mounted Kongsberg EM122 echosounder (12 kHz) during RRS Discovery cruise DY130 (Chief Scientist Susan Hartman) between March-April 2021. The cruise was conducted to map Whittard Canyon, a deep ocean canyon in the Bay of Biscay, and the Porcupine Abyssal Plain Sustained Observatory (PAP-SO), a fixed-point, open-ocean, scientific observatory. The data were edited using Caris HIPS software by Catherine Wardell and gridded at 50 m spacing in a WGS84 UTM Zone 28N. The vertical datum of the data is matched to mean sea level (MSL). They were exported as longitude-latitude-depth triples. Funding was provided to CLASS (Climate Linked Atlantic Sector Science), the National Capability Single Sector Marine Research Programme by NERC.
